Biology
Review AI-generated biology work — cell biology, genetics, ecology — at the STEM tier.
Biology — Up to $40/hr
Tier: STEM
Biology subcontractors review AI-generated answers across cell biology, genetics, ecology, evolution, and human physiology. Models often produce explanations that mix correct mechanism with wrong scale — cell-level reasoning applied to whole-organism questions, or vice versa. We test for the disposition that keeps the scales straight.

About the specialty
Biology review work pays at the STEM tier. The hardest model errors aren't factual — they're scale errors, where the mechanism described is real but operates at the wrong level. We test for the disposition that catches both kinds of mistake.
Topics covered in the test
The Cognition Test for Biology draws from a 150-question bank covering cell biology, genetics and molecular biology, ecology and evolution, human physiology, and selected topics in microbiology.
Difficulty mix
10 easy / 20 medium / 10 hard in the domain section. Behavioural section unweighted by difficulty.
Sample question topics
Cell-cycle checkpoint review; Mendelian inheritance ratios; ecological-niche reasoning; identifying model-generated explanations that confuse cellular and organismal scales.
What we test for
Scale literacy and mechanism reading. The hardest biology model errors are the ones where every individual claim is true but they don't compose into a coherent answer.
After you pass
Qualified Biology subcontractors are matched to live AI review work within seven days. Rate ceiling is up to $40/hr at the STEM tier.
